Female Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly SpinnerFemale Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Spinner View 6 PicturesI'm not sure of the species of this female spinner, and unfortunately I never found the associated males or duns to aid in identification. The egg-laying flight and fall of fairly large clouds of these females caused good rises of choosy trout for a week or so around early July on a large, cold spring creek in the northwoods. There is a distinctive stripe down the female's back, identical to that on this specimen collected a month later.

Ephemerella excrucians (Pale Morning Dun) Mayfly NymphEphemerella excrucians (Pale Morning Dun) Mayfly Nymph View 5 PicturesI spent (Spent: The wing position of many aquatic insects when they fall on the water after mating. The wings of both sides lay flat on the water. The word may be used to describe insects with their wings in that position, as well as the position itself.) a while with a microscope to fairly positively identify this specimen as Ephemerella excrucians.

Cicadidae (Cicadas) Cicada AdultCicadidae (Cicadas) True Bug Adult View 4 PicturesI found this cicada and several like it in the grass near my car as I put my waders on. Some of them were singing in the trees above the river, too, but I did not see any fall into the water.

Female Ephemerella subvaria (Hendrickson) Mayfly SpinnerFemale Ephemerella subvaria (Hendrickson) Mayfly Spinner View 3 PicturesThis one's a bit bedraggled because it was rainy and I had a hard time keeping anything dry, including the container I was putting mayflies in. I was practically juggling up there balanced on a rock trying to catch mayflies and trout at the same time.

Maccaffertium vicarium (March Brown) Mayfly NymphMaccaffertium vicarium (March Brown) Mayfly Nymph View 3 PicturesI keyed this nymph to Stenonema fuscom, which is now synonymized with Maccaffertium vicarium. However, the size, markings, and time of year make me very skeptical of this identification.

My wife and I will be visiting Brule in Mid-July, staying for several days. Any advice on fly fishing spots on the Brule River would be appreciated
